Ahmad ibn Mājid (Arabic: أحمد بن ماجد), was an Arabian navigator and cartographer born in 1421 in Ras Al Khaimah (which was formerly known as "Julfar"). He was raised with a family famous for seafaring; at the age of 17 he was able to navigate ships. He was so famous that he was known as the first Arab seaman. The exact date is not known, but ibn Majid probably died in 1500. He became famous in the West as the navigator who helped Vasco da Gama find his way from Africa to India, however, the leading scholar on the subject, G.R. Tibbetts, disputes this claim. Ibn Majid was the author of nearly forty works of poetry and prose. He was also known as the lion of the sea.
Bin Majid wrote several books on marine science and the movements of ships, which helped people of the Persian Gulf to reach the coasts of India, East Africa and other destinations. Among his many books on oceanography, the Fawa'dh fi-Usl Ilm al-Bahrwa-al-Qawaidah (The Book of the Benefits of the Principles of Seamanship) is considered as one of his best. He also wrote Kitab al-Fawa'id [Book of Lessons on the Foundation of the Sea and Navigation] (in Arabic).
It is an encyclopedia, describing the history and basic principles of navigation, Lunar mansions, rhumb lines, the difference between coastal and open-sea sailing, the locations of ports from East Africa to Indonesia, star positions, accounts of the monsoon and other seasonal winds, typhoons and other topics for professional navigators. He drew from his own experience and that of his father, also a famous navigator, and the lore of generations of Indian Ocean sailors.
